Digital-S

D-9 or Digital-S as it was originally known, is a professional digital video videocassette format created by JVC in 1995. It is a direct competitor to Sony's Digital Betacam. Its name was changed to D-9 in 1999 by the SMPTE. It was used to a small extent in Europe and Asia and saw some use in the US, notably by the Fox news channel, but was a commercial failure compared with Digital Betacam. It was superseded by high definition tapeless formats.

Technical details

D-9 uses a tape shell of the VHS form factor, but the tape itself uses a much higher quality metal particle formulation. The recording system is digital and for video uses DV compression at a 50 Mbit/s bitrate. Video is recorded in 4:2:2 component format at a variety of standard definition resolutions, in either 4:3 or 16:9 aspect ratios. Audio is recorded as 16bit/48 kHz pcm with up to four separate channels. Video quality is generally very high; at standard definition, D-9's quality is comparable with Digital Betacam.
